Gardener Chart releaser

In this repo, the code for a Gardener chart releaser is provided and maintained. This software aims at collecting and releasing charts required for Gardener provisioning, so that they can be accessed at one single point of truth. Releases are published on GitHub and a corresponding helm repository is configured via GitHub pages. Consequently, working with the released charts is as simple as it could be. Note that only the software itself is maintained here. The releases are/can be published in various other repositories (you could also setup your own, if you like).

Getting Started

The configuration file

First, please checkout the config.yaml file as a starting point. The overall structure is as follows:

destination:
    owner: gardener-community
    repo: gardener-charts
sources:
    - name: gardener-controlplane
      version: v1.53.0
      repo: gardener/gardener
      charts:
        - charts/gardener/controlplane
  - ...

sources defines a list with "upstream" charts to collect, and destination defines a repository (hosted on GitHub) serving as a helm repository where the charts are released.

Export charts locally

If you want to export the configured charts to a local directory for development purposes, gardener-chart-releaser can do it for you. Simply run

go run main.go export

and find a charts directory containing the configured charts. Now, you can develop (with) these charts.

Update the versions defined in config.yaml

You can simply update the versions in config.yaml to the latest version available upstream by

go run main.go fetchLatestVersions

This is useful in combination with exporting the charts to a local directory. If you fetch the lastest versions before, the charts in the local directory will also match the latest version.

Further help

You can get further help by running the help commands implemented by the program. For instance,

go run main.go --help

or

go run main.go update --help

will provide further information.
